Step 1 -- Getting the Drive Parameters
In order for Drive Master for NT to diagnose and repair a damaged file system the software must first scan the drive for its possible setup parameters. In order to start that process use the mouse or the hotkey 'D' to initiate the Diagnostics command.

After this has been done the following menu bar will be displayed across the top of the screen. Using the mouse or the hotkey 'L' execute the Load Physical command. Drive master for NT will then begin its scan of the FIRST drive in the system. Drive Master for NT works with the primary drive only. Any subsequent drives are ignored.

When Load Physical is executed the following screen will be displayed

The Physical Drive Scan screen displays pertinent information regarding the primary drive on the current system. A description of each field is as follows:
Drive ID: This is the identification number of the drive. It should always be 80.
BIOS EDD Support: This field identifies if the current BIOS supports extended drive
access.Parameters: The head, sector, cylinder, and LBA Sectors data is critical to the
successful recovery of the hard drive. If this data is not correct then the drive geometry alignment may be out of skew and recovery becomes an impossible task. Make sure that this data is correct and matches what is in the current CMOS setup of the BIOS.If you see garbage, zeroes or the data does not align because the
damaged drive is not in its native system and the original BIOS does not match the current BIOS then use the Edit Physical command from the menu bar to update the drive settings. (please click on this link to read more first!)
